df=1 for all predictors. Based on logistic regressions (final model) predicting use of two or more medications concurrently. Sensitivity analyses using Poisson regression to predict the count of the total number of medications found the same predictors and patterns, with slightly smaller p values for several due to the greater variance in the dependent measure.
